Acts of mass violence, such as the mass shooting in Las Vegas, cause extreme disruption and can be distressful for individuals, families and communities. Those receiving assistance as well as those involved in disaster management efforts can be affected. The sheer magnitude of death and injury in a group that gathered from around the country will result in an affected disaster "community" that extends far beyond the location of the event. Individual and community strength can be enhanced by interventions that address critical behavioral health issues throughout both the response and recovery phases. Ideal interventions promote the evidence-based principles of Psychological First Aid (PFA), including: safety, calming, self- and community-efficacy, social connectedness, and a sense of hope/optimism.

Below are fact sheets that address important general principles to support individuals and communities after disasters, such as mass shootings, as well as additional topics directly relevant to the Last Vegas shootings. Click on the title to go directly to that section and applicable resources.

Grief is a near universal experience for those directly impacted by mass violence, such as the Las Vegas concert mass shooting. In the immediate aftermath, some will lose loved ones or suffer injuries themselves. Many will experience increased fear and loss of perception of safety. Loss of control and life routine often compound feelings of grief. Community leaders, those leading disaster management efforts, and healthcare providers can help affected individuals by gently inquiring about, acknowledging and then allowing individuals to process grief. Grief support also involves addressing feelings of loss, mourning losses, and fears about the future. Anxiety about the future is best managed through “problem solving” (supporting people in connecting with practical help when available). Being sensitive to the need for rituals, such as memorial and funerals, to support expressions of grief allow for healing, which ultimately strengthen communities.

Common responses to disasters include distress reactions (insomnia, irritability, loss of safety, social isolation, blaming and scapegoating) and health risk behaviors (increased use of alcohol and tobacco, reduced attention to health care). For healthcare personnel, being alert to these reactions and behaviors, promptly identifying them, and providing interventions can reduce distress and improve functioning and may decrease the likelihood of ultimately developing mental disorders. Normalizing the reactions and offering anticipatory guidance about what to expect with symptoms over time, as well as when to get help and where to go, help people feel calm and enhance feelings of efficacy.

Special populations may be more vulnerable than others and warrant unique considerations. Such populations include: children, women, cognitively and mobility impaired, pre-existing mental health conditions, first responders and public health emergency workers (including volunteers). Children will need support and monitoring at home and at school. Partnering with community leaders, healthcare organizations, and local schools create opportunities to provide education and resources as well as support community efforts to reduce distress and enhance well-being. Focused interventions can more quickly and effectively address the unique needs of these populations. The following resource(s) address this topic in further detail:

Health risk and crisis communication is a critical behavioral health intervention following a community disaster. For those leading disaster management efforts, understanding what to say and what not to say, when and how to say it are important elements. Basic principles include being clear and succinct; stating what is known and unknown; indicating when you do not know the answer, committing to following up at a specific time and then doing so; avoid lying or efforts to be overly reassuring as these erode trust. Effective communication following a disaster can reduce distress and enhance well-being for affected communities. The following resource(s) address this topic in further detail:

Workplace management following a disaster is an important part of restoring community functioning. In addition to financial support, the workplace often provides a sense of meaning and social connectedness. Effective support for personnel in the workplace can enhance functioning for both the individuals and the organization. The following resource(s) address this topic in further detail:

Additional detailed resources can further knowledge about effective preparedness, response, and recovery measures. Some are brief while others are more detailed. While reading more detailed resources, such as books about disasters, during an actual disaster response is not likely to happen, they are much more in depth treatments of key topics that may be helpful as the initial response slows a bit to assist with immediate response and recovery and enhance preparedness for future events.
